Key Parameters

Substitute Part Grouping Explanation

Substitution of the OVFSG7C8 is determined by the following critical parameters:

• Package compatibility: 4-DIP (0.200", 5.08mm) through-hole configuration
• Color specification: Green LED indication
• Wavelength range: Green spectral output (525–527nm acceptable)
• Electrical characteristics: Forward voltage and test current compatibility
• Viewing angle: 70° standard viewing angle
• Mounting type: Through-hole PCB mounting
• Regulatory compliance: ROHS3 and REACH status

The XSM2DG983W from SunLED meets all substitution criteria through matching package geometry, green wavelength output (525nm typical), compatible electrical ratings, and equivalent regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The XSM2DG983W is a direct functional substitute for the obsolete OVFSG7C8. Both components share identical package geometry (4-DIP 0.200"), matching mounting type (through-hole), equivalent viewing angle (70°), and identical test current (30mA). The wavelength specifications are within the green LED spectrum range (525–527nm), ensuring visual compatibility in indication applications.

The XSM2DG983W offers the advantage of active product status with current manufacturing availability, whereas the OVFSG7C8 is obsolete. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. The forward voltage differential (3.3V vs. 3.6V) is within acceptable tolerance for standard LED indication circuits and does not preclude substitution in typical applications.

Frequently Asked Questions (FAQ)

Q: Can the XSM2DG983W be used as a direct replacement for the OVFSG7C8 in existing designs?

A: Yes. Both components share identical 4-DIP (0.200", 5.08mm) package geometry and through-hole mounting configuration. PCB footprints are compatible. The 0.3V forward voltage difference (3.3V vs. 3.6V) is within standard LED circuit tolerance and does not require design modification.

Q: Are there wavelength differences between these parts?

A: The OVFSG7C8 has a dominant wavelength of 527nm, while the XSM2DG983W operates at 525nm typical. Both fall within the green LED spectrum and produce visually equivalent green indication output.

Q: What is the height difference between these components?

A: The OVFSG7C8 has a maximum height of 5.94mm, while the XSM2DG983W is 4.65mm maximum. The XSM2DG983W is shorter and will fit within any clearance envelope designed for the original part.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the OVFSG7C8 and XSM2DG983W are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What is the primary reason for substitution?

A: The OVFSG7C8 is obsolete and no longer manufactured. The XSM2DG983W is an active product with current manufacturing availability, ensuring supply chain continuity.
